“(Acting movies) isn’t acting; that’s piecework. You’re not human being, you’re a thing in a vacuum. Noise shut out, human response shut out. But in the theater, when you hear that lovely sound out there… it’s as though they’d turned on an electric current that bit you here. And that’s how you learn to act.”
Edna Ferber and GeorgeS. Kaufman.
